Question

In the sketches attached follow the load path from the top floor to the ground columns. find the loads on the beams in (kN/m) and the columns in (kN). the frame is non-rigid Ignore the weight of the members.

2 tone tonn ne ya

Answer 1

Interior Portal Load Path from Top Floor to ground column Frame nm - n gcd neglect wt. of member spacing of portal = 15m Tributary width = 15m (1) (Roof) Top floor = 1 N/m^2 Therefore beam w = 1 times 15 = 15 kN/m (2) 2nd Floor w_beam 2 times 15 = 30 KN/m (3) First floor w_beam = 1 times 15 kN/m consider all spans to be simply support Reaction at end of each beam = Wl/2 End Portal Tributary width = 7.5 m
